* Rework internal bus handling and laptop bail-outNico Huber2019-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | We used to bail out on any unknown laptop. However, modern systems with SPI flashes don't suffer from the original problem. Even if a flash chip is shared with the EC, the latter has to expect the host to send regular JEDEC SPI commands any time. So instead of bailing out, we limit the set of buses to probe. If we suspect to be running on a laptop, we only allow probing of SPI and opaque programmers. The user can still use the existing force options to probe all buses. This will obsolete some board-enables that could be moved to `print.c` in follow-up commits.

| | | | | | | | | | | | | | | | | | | | | Get rid of the layering violations around ICH's BBAR. Move all the weird address handling into (surprise, surprise) `ichspi.c`. Might fix writes for the `BBAR != 0` case by accident. Background: Some ICHs have a BBAR (BIOS Base Address Configuration Register) that, if set, limits the valid address range to [BBAR, 2^24). Current code lifted addresses for REMS, RES and READ operations by BBAR, now we do it for all addresses in ichspi. Special care has to be taken if the BBAR is not aligned by the flash chip's size. In this case, the lower part of the chip (from BBAR aligned down, up to BBAR) is inacces- sible (this seems to be the original intend behind BBAR) and has to be left out in the address offset calculation.

* Add support for Intel Silvermont: Bay Trail, Rangeley and AvotonDuncan Laurie2014-08-201-6/+8
| | | | | | | | | | | | | | | | | | | | | | The core of this patch to support Bay Trail originally came from the Chromiumos flashrom repo and was modified by Sage to support the Rangeley/Avoton parts as well. Because that was not complicated enough already Stefan Tauner refactored and refined everything. Bay Trail seems to be the first Atom SoC able to support hwseq. No SPI Programming Guide could be obtained so it is handled similarly to Lynx Point which seems to be its nearest relative. Corresponding to flashrom svn r1844.

* Refine Flash Component descriptor handlingStefan Tauner2014-08-201-9/+21
| | | | | | | | | | | | | | | Possible values as well as encodings have changed in newer chipsets as follows. - Pre-PCH (i.e. ICH) chipsets had a maximum frequency of 33 MHz for all operations - Since Cougar Point the chipsets support dual output fast reads (encoded in bit 30). - Flash component density encoding has changed from 3 to 4 bits with Lynx Point, currently allowing for up to 64 MB chips.

* ichspi: fix missing set_addr on erases and possible crossings of 256 B ↵Stefan Tauner2014-08-051-0/+8
| | | | | | | | | | | | | | | | | | boundaries Apparently the erase function did never set any address before issuing the erase commands. How could this ever work? Also, according to PCH documentation crossing 256 byte boundaries is invalid and may cause wraparound due to the flash chip's pages. Check for this on reads as well as writes.

| | | | | | | | | | | | Register_programmer suggests that we register a programmer. However, that function registers a master for a given bus type, and a programmer may support multiple masters (e.g. SPI, FWH). Rename a few other functions to be more consistent.
